Filter transformator for redux-persist
npm install redux-persist-transform-filter
import { createFilter, createBlacklistFilter } from 'redux-persist-transform-filter';
// this works too:
import createFilter, { createBlacklistFilter } from 'redux-persist-transform-filter';
// you want to store only a subset of your state of reducer one
const saveSubsetFilter = createFilter(
'myReducerOne',
['keyYouWantToSave1', 'keyYouWantToSave2']
);
// you want to remove some keys before you save
const saveSubsetBlacklistFilter = createBlacklistFilter(
'myReducerTwo',
['keyYouDontWantToSave1', 'keyYouDontWantToSave2']

// you want to load only a subset of your state of reducer three
const loadSubsetFilter = createFilter(
'myReducerThree',

// saving a subset and loading a different subset is possible
// but doesn't make much sense because you'd load an empty state
